STREET-CLEANER.

Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed January 9, 1912. Serial No. 670,329.

To all whom it may concern:

Be it known that I, JOHN B. GRAVELLE, citizen of the United States,residing at Asbury Park, in the county of Monmouth and State of NewJersey, have invented certain new and useful Improvements in Street-Cleaners, of which the following is a specification.

This invention relates to street cleaners, and has for its object toprovide a cleaner in the form of a barrow adapted to be propelled overthe surface of the street and provided with a rake attachment for thepurpose of moving material from the surface of the street up into thebody of the barrow.

A further object of the invention is generally to improve this class ofdevices so as to increase their utility, durability and efficiency.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing, in which: 7

Figure 1 is a perspective view of the cleaner; Fig. 2 is a sectionalview of the same; Fig. 3 is a bottom plan view of the cleaner; Fig. 4 isa perspective view of portions of the cleaner, showing the manner inwhich the rake operating rods may be interlocked.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingby the same reference characters.

The cleaner includes a body 1 which constitutes a barrow, formed fromsheet metal and shaped up as will be explained hereinafter. The saidbody 1 is mounted upon wheels 2 which are located in the vicinitv of therear edge thereof. Handles 3 extend rearwardly from the body 1 and areconnected together by a cross bar 4. Each handle 3 is provided at apoint near the body 1 with a grip 5. The said grips are disposedinwardly with relation to the said handles. The body 1 is provided atits sides and at its forward end with eyes 6 to which trace chains maybe attached when it is desired to move the cleaner by the use of a draftanimal. The body 1 is formed from a blank having a bottom portion 7,side portions 8 and an end portion 9. Reinforcing angle irons 10 areapplied to the meeting edges of the sides 8 and bottom 7 and the end 9and bottom 7. A stiffening strip 11 is applied to the under forward sideof the bottom 7 and a strip 12 is applied to the upper side of the strip11 so that the upper surface of the strip 12 is flush with or in thesame plane approximately as the upper surface of the bottom 7. hen thestrip 12 is worn to such an extent as to be useless it may be removedfrom the strip 11 and a new one substituted in its stead.

Guides 13 are mounted at the upper edges of the sides 8 and a rod 14 islocated between the said guides and the upper edges of the sides 8. Thesaid rod is held against longitudinal movement with relation to the saidsides by means of heads 15 fixed at the ends thereof.

A rake member 16 is mounted upon the rod 14 and is provided with anupwardly and forwardly projecting arm 17. A guide 18 is mounted upon theend 9 and a rod 19 passes through the said guide 18 and is pivotallyconnected at its forward end with the upper end of the arm 17. The rod19 is provided at its rear end with a grip 20 and at a point in thevicinity of its rear end with a laterally disposed lug 21. A bail 22 isattached to the upper portion ofthe rake 16 and extends rearwardlytherefrom. A rod 23 passes through the guide 18 and is pivotallyconnected at its forward end with the intermediate portion of the bail22. The rod 23 carries an eye 24 which slidably receives the rod 19. Therod 23 is provided at its rear end with a grip 25 and at a point in thevicinity of its rear end with a laterally disposed lug 26.

It will be seen that the body 1 may be propelled over the surface of thestreet and brought in contact with the material lying thereon, and bymoving the rods 19 and 23 through the guide 18 the rake 16 may be disposed over the said material. By moving the rods 19 and 23 alternatelyin opposite directions the rake 16 will be swung upon the rod 14,whereby the said rake will encounter the said material and sweep thesame back upon the bottom 7 of the body 1. By drawing the rods 19 and 23rearwardly at the same time the said rake will pull the material backtoward the end 9 of the said body.

As illustrated in Fig. 4 of the drawings the lugs 21 and 26 carried bythe rods 19 and 23 respectively may be interlocked with each other sothat by pushing the rod 19 the rod 23 will be moved longitudinally in aforward direction, and by pulling the rod 23 the rod 19 will be movedrearwardly. Thus the rake member 16 will be moved bodily without tiltingor swinging the same upon its supporting rod 14.

In some instances where the surface of the pavement or street is notlevel but is rounded in an upward direction, it is desirable to slightlybuckle the body 1 so that the strip 12 will fit snug against the bowedsurface of the street. To accomplish this, ears 28 are located at theends of the body 1 and rod sections 29 are connected with the said ears.The inner ends of the said rod sections 29 are connected together by aturnbuckle 30. A rod 31 is provided with branches 32 which are connectedwith the rod sections 29 beyond the ends of the turnbuckle 30. The rod31 is connected at its rear end with a lever 33 which is pivoted to thebottom of the body 1 and which is arranged to engage a dentate member34, also attached to the body 1. Therefore it will be seen that byswinging the lever 33 the rod 31 will be moved longitudinally, wherebythe inner ends of the rod sections 29 may be swung rearwardly and thusthe said rod sections are moved out of alinement with each other. Thismovement on the part of the said rod sections will have a tendency tobuckle or arch the bottom 7 of the body 1, so that the strip 12 willfitsnugly along the surface of an arched pavement.

Members 35 are pivotally attached to the end walls 8 of the body 1 andwhen not in use may be swung upwardly and inwardly within the said wallsas indicated in Fig. 4 of the drawings. hen these members are in usethey are swung so that their forward port-ions project in front of theforward edge of the strip 12 as indicated in other and adapted to bemoved to swing the rake and move the rake along its sustaining guides.

2. A cleaner comprising a body having sides provided with guides, a rakesupported in the guides, a guide mounted upon the rear end of the body,and rods slidably received in the last mentioned guide and guided withrelation to each other by an eye carried by one of the said rods, saidrods being connected at their forward ends with the rake at the oppositesides thereof.

A cleaner comprising a body, rods connected with the ends thereof, and alever mechanism mounted upon the body and connected wit-lithe said rodsto move the same to buckle the body.

1. A cleaner comprising a body, rods connected with the ends thereof, aturnbuckle connecting therods together, a lever mechanism mounted uponthe body, and a rod connecting said lever mechanism with the firstmentioned rods.

In testimony whereofI affix my signature in presence of two witnesses.

JOHN B. GRAVELLE.
